This invention has reference to a compound of matter-for use-in connection with the tanningof hides, its object being to provide a compound wherein the ingredients are inex ensive andwhereb thetanned 7 leatherris firm, flexible and waterproof.

The ingredients employed comprise fluid extract of deeoction of yellow dock, fluid extract of bugle weed, (Lg 00pm Virginicuc), extract of catechu, fluid extract ofhemloclc bark and gambier. While it is not mandatory thatany exact formula as to the quantities of these several ingredients be followed, practice has demonstrated that excellent results are, obtained by the following proportions of the ingredients used in the manner'stated. For calf, wolf,f

sheep, goat, deer and hides similar in size and weight, there are employed three galions of strong decoction of yellow dock roots, or three gallons of-water to which has been added one pound of fluid extract of yellow dock, then add one ounce orf'tluid extract of bugle weed, one ounce of the ex-.

tract of catechu, and one ounce of fluid extract of hemlock bark. The hide is immersed in such fluid and allowed to remain therein for twenty-four hours to color and set the grain. The hides are now removed and to the fluid is added one pound of gum ga'mbi'er. dissolved, preferably in a new tin,- brass or copper vessel and then cooled and strained. The hide or hides are then replaced in the compound and allowed to remain until tanned, this last process taking from twelve to twenty-four hours in addition to the firstimmersion'; For larger and heavierhides, such as yearling and two year hides, there are employed five gallonsot a strong decoction of yellow dock roots, or one and one-quarter pounds of fluid extract of yellow dock in five gallons of water, and to thisis added two ounces each of fluid extract of bugle" weed, extract of catechu and fluid extract of hemlock bark. The hide or hides remain. in this solution for twenty-four hours to color and set the grain, after which the hide is removed and from oneto two pounds of gambier are added when the hide is replaced and allowed to set until tanned, which will take from three to five days in addition to the first immersion. For horse, cow, ox, bear and all other large hides from five to seven gallons of a strong decoction of yellow dock roots is employed, or five to seven gallons of water and one and one-half to two pounds of fluid extract of yellow dock. To this is added four ounces each of fluid extract of bugle weed, extract ot catechu; and fluid extract of hemlock bark.

follows: The hides are soaked until perremoved. They are then immersed in a very thin batter of slakcd lime and water in which they are allowed to remain from four to twenty-four'hours, or until the hair slips. thchidesbeing taken out of the lime and replaced therein several times for the r from the lime and the hair removed.
